我正在尝试将GraphFrames添加到我的scala spark应用程序中，当我添加基于2.10的应用程序时，这很顺利。但是，一旦我尝试使用GraphFrames构建scala 2.11构建它，它就会崩溃。
问题是使用了冲突的scala版本（2.10和2.11）。我收到以下错误：
[error] Modules were resolved with conflicting cross-version suffixes in {file:/E:/Documents/School/LSDE/hadoopcryptoledger/examples/scala-spark-graphx-bitcointransaction/}root:

但是，我无法解决导致此问题的原因。这是我的完整版本.sbt：

任何人都可以确定哪个依赖项基于 scala 2.10 导致构建失败？
我发现了问题所在。显然，如果您使用：
libraryDependencies += "org.apache.spark" %% "spark-core" % "1.5.0" % "provided"
默认情况下，它使用 2.10 版本。一旦我将 Spark 核心和 spark graphx 的依赖项更改为：
libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.2.0"
libraryDependencies += "org.apache.spark" % "spark-graphx_2.11" % "2.2.0" % "provided"
